ISO 26429-6:2008定义了加密的数字电影非交错材料交换格式（MXF）帧包装轨道文件的语法，并指定了匹配的参考解密模型。它使用高级加密标准（AES）密码算法进行本质加密，也可以选择使用HMAC-SHA1算法进行本质完整性加密。数字电影轨道文件格式旨在将数字电影精华传送到展览现场，并在声音和图像轨道文件规范中进行了规定。 ISO 26429-6:2008假设解密和验证加密轨道文件完整性所需的加密密钥将根据需要提供。更准确地说，它没有规定在数字电影发行和展览环境中管理加密密钥和使用权的方式。 此外，ISO 26429-6:2008并未涉及但不排除使用水印、指纹或其他安全技术来提供额外保护。 该范围仅限于数字电影，未定义通用的MXF加密框架。

ISO 26429-6:2008 defines the syntax of encrypted digital cinema non-interleaved material exchange format (MXF) frame-wrapped track files and specifies a matching reference decryption model. It uses the advanced encryption standard (AES) cipher algorithm for essence encryption and, optionally, the HMAC-SHA1 algorithm for essence integrity. The digital cinema track file format is designed to carry digital cinema essence for distribution to exhibition sites and is specified in the sound and picture track file specification. ISO 26429-6:2008 assumes that the cryptographic keys necessary to decrypt and verify the integrity of encrypted track files will be available upon demand. More precisely, it does not specify the fashion with which cryptographic keys and usage rights are managed across digital cinema distribution and exhibition environments. In addition, ISO 26429-6:2008 does not address, but does not preclude, the use of watermarking, fingerprinting or other security techniques to provide additional protection. The scope is limited to digital cinema and does not define a generic MXF encryption framework.
